{"jsonrpc":"2.0","id":1,"method":"tools/list"}gsa_labor_rates — GSA schedule hourly labor rates for a job title — the ceiling rate vendors may charge the government under a GSA MAS contract. Use this to benchmark what a labor category costs: "typical GSA hourly rate for a project manager", "what do senior software engineers bill under MAS", "GSA schedule rate for a data scientist with 10 years experience". Returns individual rates with vendor name, contract number, SIN, education and experience requirements, plus a price summary (min, p25, median, p75, max) computed across EVERY matching rate, not just the ones returned. Filter by experience, education, worksite, business size, security clearance and price band. Example: gsa_labor_rates({ labor_category: "software engineer", min_experience: 5 })gsa_rate_stats — Price statistics only for a GSA schedule labor category — min, 25th percentile, median, 75th percentile and max hourly ceiling rate across every matching contract rate, with no individual rows. Use when you want the benchmark number rather than the listings: "what is the median GSA rate for a business analyst", "p75 hourly rate for cybersecurity engineers with a clearance". Same filters as gsa_labor_rates. Example: gsa_rate_stats({ labor_category: "project manager", education: "BA", min_experience: 10 })gsa_vendor_rates — Every GSA schedule labor rate published by one contractor — what this specific company charges the government per hour, across its labor categories, with contract numbers and SINs. Use for "what rates does Booz Allen have on its GSA schedule" or to compare one vendor against the market median. Example: gsa_vendor_rates({ vendor: "DIGNITAS TECHNOLOGIES" })Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
